  • the good co-existence between operators and especially interference towards victim LTE TDD may be improved or assisted with one or more of the following actions by NR TDD BS and NR TDD UE using NR TDD SUL on a given frequency band (as an example frequency band):
  • NR BS detects and measures what is neighbor operator's UL/DL configuration, e.g., what slots are used for DL and which slots are used for UL on the adjacent frequency typically on the same frequency band.
  • ⁇ NR BS and NR UE may be hearing/detecting different neighbor operators base stations due to uncoordinated deployments between the operators. Thus, it may be, at least in some cases, beneficial that both NR BS and NR UE attempt or try to detect neighbor operator's TDD UL/DL configuration. In this way an increased likelihood is provided that neighbor operator' s signal and its DL/UL are detected if there is any in the neighborhood.
  • NR BS If either NR BS or NR UE detects neighbor operator' s TDD UL/DL configuration, NR BS can safely use all the neighbor operator's UL slots for its UL transmission to ensure similarly synchronized operations as assumed between LTE TDD operators and thus avoiding co-existence issues.
  • the NR UE attempts to detect during neighbor operator' s UL slots whether it can hear any UE's transmission in the neighbor operator's system and frequency.
  • the NR UE knows the neighbor operator's UL slots either based on its own earlier measurements or alternatively based on information received from the NR BS during signaling (e.g., radio resource control/RRC signaling). These detections may typically need to be sufficiently long or sufficiently many separate detections are done, in order to make sure that the NR UE does not just happen to try to do the detection during the idle transmission periods of neighbor operator' s UE.
  • the NR UE does not hear/detect any neighbor operator UE' s transmission after several attempts over period of time and neighbor operator has relatively symmetric DL/UL allocations, e.g., not DL broadcast only, the NR UE informs the NR BS (that it cannot detect neighbor operator UE's transmission) and then the NR BS can take many of the neighbor operator's DL slots for UL use on its supplementary UL for a given UE without creating too severe co-existence issue.
  • NR BS may avoid scheduling NR UEs during time periods when neighbor cell may be transmitting critical broadcast information such as transmission of system information or management information blocks.
  • - NR UE may receive an indication then from the NR BS, of which uplink resources it may use on supplemental uplink/SUL channel (uplink grant is one but which time slots are available for PUCCH use to report HARQ ACK/NACK or CQI)
